Features of This Unit
Belt drive
A new drive system is introduced, in which motor-derived
noise is attenuated via a belt and smooth rotation is achieved.
Circuit configuration
AC synchronous motor is driven by sine waves coming from
32-bit microprocessor, which are DA converted and amplified
by a high-power audio amplifier.
Stroboscope
This unit is equipped with a reflective view type LED strobo-
scope to adjust the rotation speed precisely.
Arm base
This unit is finished with chromeplated and spin-stabilized
brass with 20 mm in thickness.
By replacing with the optional arm base, various types of tone
arms can be mounted, which allows users to enjoy sound
changes.
Tone arm
A universal static balance tone arm is included as a standard
equipment for the simple cartridge replacement.
Heavyweight platter
The platter weighs 5.0 kg, which is machined from aluminum
metal to improve rotational accuracy.
Approximately 0.7 t·cm
2
of moment of inertia has been
achieved.
High rigidity main chassis
This unit uses an underslung vibration-damping structure ca-
pable of hanging internal main parts using machined alumi-
num plate with 15 mm in thickness as a base.
Large-sized spindle
This large-diameter spindle is equipped with polyether ether
ketone (PEEK) bearing of ball bearing specification that pro-
vides stable rotation.
